TO ALL WHOM IT MAY CONCERN:

Be it known that I, CnAnLns F. PIKE, of' the city and countyof-Providence, State of Rhode Island, ha've invented' a new and improvedCorpse-Preserver for the preservation of the' dead; and I do herebydeclare that the following is a full and exact description thereof',reference being had to the accompanying drawings, and toA the letters ofreference marked thereon.

The nature of my invention consists in having a metallic case, made oftinned copper or other metallic substance, (the outside casemay be madeof wood and lined inside with vsome metallic substance,) in 4form toreceive the remains of a dead person, with a wire 'basket inside of themetallic case for the body to be deposited in; and upon the outside ofthel basket,and within 'the walls of the case, tubes or pipes, filledwith ice, or ice and salt, or with any other well-knownfreezing-mixture; also `a pan for these tubes or pipes to be fastenedto. Over this wire basket is a cover that covers tho person all over,with ribs on it, hollow pockets, or airpassages open at each end intothe pans, to'which are attached the tubes or pipes. Upon the under sideof this inner cover are openings into the pocketsor airfpassages, to let4the air into this pau that 4is attached to the pipes or tubes. Thebottom of these pipes or tubes may or may not be opened to let this airout into the chamber in which the basket sets that contains'the personto he preserved. This inside cover is covered'with ice; and then thereis still another cover that covers over all 'the pipes ortubes-, and`sol protects it from the outside' air, as

will bc seen by reference to the accompanying drawings'and specificationhereunto annee-red.

To enable others skilled in the arts'to make and use my invention, Iwill 'proceed to describe its construetion and operation. l n

Figure 1 is a ground-plan of the corpse-preservar.

B is the wire basket, that is made-of wire on the bottom, lends,isirles,about-one-tenthof an inch in diameter,

with meshes, 'two inches apart; .l Across the bottom are cleats, halfinch square, so as to keep it 'up fromthe bottom of the case, and-allowa free circulation of air under it. This basket is'made of the properlength,

width, and depth to hold a person.l The object of this basket'isvtovkeep thebody up out of the water, andthe. clothingpthat is upon theperson from coming in contact with the pipes or tubes, with a freecirculation of airl around Sit, in a dry atmosphere. D is an outsidecover, with a lip -on v'its edge that shuts over the whole of thecorpse-preserver; and for a more full 'description of" this coverreference is madeto the description -hereafter to be made of gs. 2 and3. C is a cover overthe basket, with a lip on its lower edge vthatshuts'into the pan H: The form of this cover will be more fullydescribed inthedescription of figs. 2 .and 3.- -E are the tubes or pipeswhich surround the basket, and are filled with ice, and extend downtothe bottom of thc-inside case,

with or without bottoms to them, with or without openings in the sidesof the'pipes or tubes. These tubes lor` H is a'pan,

pipes are about si-X Vinches in diameter, although they may be made ofany size or form' or shape. about six inches wide, with a ange on theoutside edge,'(the width of'- the flange is the thickness of the casebctwccn the-inside and outside walls,) extending all around it, to whichthe tubes or pipes Eare attached. This pan is about 'one inch deep; itlcan bemade deeper if yit'uis thoughtv to be important; this willanswcr'all practical purposes. b are the hoops between'thcA inside andvoutside case, of any form' that you desire them'to be made. I get out awooden bottom, and then form the hoops on that, making them in twopieces, and fastening the ends together in the centre v I I Figure 2 isa longitudinal section -on line a and b in tlg. 1.

A is the chamber or interior space of lthel prcserver that contains thewire basket B, tubes or pipes E, pan

H, and is the room that contains the corpseto be preserved. lBis thewire basket, which is made of wire, one

tenth of an inch iii-diameter; the meshes are in diamond form, about twoinches apart. This basket hasno wire cover; the cover C is the cover tothis basket. The length, width, and depth are'of any desiredv length,

width, or depth. For the largest size preservcr the basket wouldnot berequired more than' six feet four inches long by ten inches deep andtwenty-four yinches wide. The shape of the cover would give some four tosix inches more depth, as will be seen by reference to the drawing.. C'is the metallic `cover that' shuts-over the basket that contains thecorpse. This cover has alp to it ou o'ne edge, which shuts into thepanH, and-'has a' tower or pipe attached to it that extends upthrough theoutside cover D, represen-ted by the letter F. This tower or pipe is apart ofthe room A. It has also hollow pipes-on the outside of this coverC, that are open at both ends. There are also openings into these hollowpipes from the room A. These hollow pipes arerepresented. by? the letterc, from the room A, by the -letter o'. The fornrof this cover isrounding on the ends, the same as the sides, to let theiceand water slipoil` into the pipes E, to keep them supplied with ice. This metalliccover may be made 'of copper, tin, oriron. If of iron or tin, it hadbetter be kept well painted.l lD is the outside cover, made of metal,either iron, tin, or copper, (if it weremadefdouble, and illed'ivithhair'or wool, it would improve it much, and be a great saving of ice,)and, in form, so as to Acover over the-outside case, -with a lip on itto shut down about two.inches, more or less, upon the sides. VIn thisdrawing, it Aismade in the same form as the cover C, in order to give auniform space between the lids C and D. rlhrough this ou'tside cover Dis anropening to admit the tower or pipe F, that has a glass inserted init for the purpose ot' looking into the chamber A, to see the corpse,Without removing the lids. This-cover D fits asclose as possible, toallow it .to go free and'easy. It would be n. good'plan to haven rubberring to go over this tower or pipe F, to shut down close on to the'cover D to prevent the air from passing in onto the icebetweenfthe lidsor covers G and D. E are the pipes or tubes, together with'the pan H,extending from the top of the preserver down to the inside bottom of thecasel These tubes or .pipes E may be made with or without a bottom.4Ifvwith a bottom, there should be a hole inthe bottom or side to let thewater out; if without 'a bottom, 'the inside bottom to the case 'makesthe bottom. These pipes may have holes in the sides near the bottom', ormay not, Vas may be desired, (as shown in g. 2,) to let the air out. Fis 4the tower or pipe that is fastened to the lid C. It extends upthrough the lid or cover D, and is round or in oval form, or shaped toadmita glass to `look upon the face of the corpse that lies in the roomA,- without removing the lids orcovers C and D, oradmitting anyexternalair to the room A. This tower F should be made tight on the` lidC-tn prevent anywa-ter from the ice melting upon the lidC, running intothe room A, around the, pipe or tower Gis the broken 4ice resting uponthe lid' C, and between the lids, or covers C and D. As this ice melts,it runs Yinto the tubes or pipes E, and so on inits/ natural' conrse'toits outlet; 'and if the ice in the tubes E becomes wasted aivay'inll thepipes orrtubes, this icel upon the lid or cover C is scraped down intothe tubes or pipes E to replenish them. His the pan that extends aroundthe inside ofthe chamber A, and between the basket B, with a. iiange'onit, on thel outside edge, to rest uponV the top ofthe case. This ilange.is as wide as the case is thick. T-this pon H,`whi'chis eine inch deep,more or less, a'rethe pipes or tubes attached or fastened either by avcollar on the under side of thepan, to slip into the pipe or tube E, orsoldered tight to it. I is the outside metallic case, made'of tinnedcopper, or other metallic substance. It may be made of wood; but myjudgment and experience are that copper, about one and o quarter poundto a'squarefoot, is the best.l This outside case wants lto be tight; thelength, width,and depth, may be varied, according to the size ofthe'person. A'good size, where you do not have but one, is seven feetsixinches long; depth, about ten inches inside; width, about'thirty-iiveinches inside of the case; yJis the inside caso or liningmade of copper,l,about one pound to the square foot. 4This, case isone inch smaller allaround sides and ends, on thebottom, Vthan the case I. j Between thecases. and J'v there` are strips, put crosswise,l to support the bottomof thel inside case J. lK is a strip that connects theinside case J withthe outside case I, and -has a. ange turned down inside and outside, andis solderedtght tothe cases I'J. b are the hoops between the inside andoutside cases I J, one :1t-the bottom of the insidecase 1J, oueatthetop, between the cases I'and J, andthe other iu themiddle, .between thetwo. The object of'thcsc hoops isfto press the outside 0f the metalliccase entf-and .keep itin form-and shape. e'is the'l space between theinside and outside case, which islled withanou-conducting substance,such as wool, hair, or air. N isa ivooden bottom, about ,one-y half inchthick, that covers the whole bottom of the corpse-preservar whenmadeof'thin metal. y The object ot' this is tokeep the bottom of themetallic case from being bruised. This wooden'bottom. is fastened tothis corpse-preserver by pieces of copper soldered to the :sides of thepreserver, and extending down on toA this wooden bottom, and nailed orscrewed-to it on the edge. g are the cleats, one-half inch thick, thatare fastened' crosswise to the wooden bottom tol prevent the woodenbottom from springing'or warping outfof shape. P is the 'pipe/thatconne-cts to the inside casing J", and lextends down throughthe-outside'case vL (being soldered tight to that casing 1,) through thewooden bottom N and 'cleat g. The object of this pipe PY is to take o`the waste water from the melting of the ice. There may be any of thewell-known forms ot' traps attached to this pipe P, to prevent the airfrom passing into4 the room A, but which will not obstruct the waterfrom running off lfrom the pipe P. i

Figure Sis section. online c and d, in 5g". 1.

Ais the chdmber that contains the tubes or pipes E, wire basket B, andthe corpse. C is the cover, which is fully described in fig. 2; but alsthat-view will not show the operatouof the air from 'the chamber Athrough the hollow pipes attached to thecover C,V down'through-the pipesor-tubesrE, und ontat the 'holes'in the sides ofthe pipe E intotheehamber A, I-wll describe it here," as that is unimportantarrangement, whether itis used as a Whole or as a part.

When the corpse is laid in the basket, the coldest air will be in thebottom of the chamber 'A, the warmest in the top. The object ofthe'openings in the cover C, and the hollow pipes attached tothecover'C, with their` ends open, is, as the air is warmed by coming incontact with the body, that it will rise in the chamber A, iiow into thehollow pipe c, and pass out at the ends of these hollow pipes into the'pan H, and thence down the pipes or tubes E out of the holes in thepipes or tubes E, near the bottom, into the chamber A, and it willsocontinue 'to rotate so long as there is ice in the pipes or tubes E.'The holes in the pipes or tubes E are represented .bythe letter o. Theobject of this cover C being made in this form is threefold: first, thatthe meltings from the cover shall run throughthe pipes ,or tubes Esecond, if you have a large, corpulent person', you can put himin itwith out having the cover press upon him, although the preservcrisshallow; the third is that you; can sec the body withouthexposing itto the external air; or, if you wish to re-c'harge it with'ice, you haveonly .to take oli' the outside cover D. E are the pipes or tubesdescribed in full in fig. 2", and only lneed to sayv here that there maybe one tube extending around the case on the inside, with u. circulationof air, but it would not have the surface of the row of tubes or pipes.This form ofthe icc-box may be changed in several ways.

All the other letters in this figure seem to be fully described and setforth in the preceding description of those, figs. 1 and 2.

For the construction of these pipes or tubes, and their connections andVappendages, I refer to'the specieations und drnwings of former patentsissued to mc, and ,bearing the dates as follows, viz, June 12 :indDecember 18 A. D. 1866; January 1 and December 10, A. D. 1867. y

The forms ofthe onse may be changed to suit the eye orlfunvcy of theconstructor. I have endeavored to give the best plan, so far as myexperience upon the use of them has been. A. good freezing-mixture istwenty pounds of the bcst coarse salt to cightypounds of ice, althougha. less amount of salt will do. When one is constructed likethevdrawing, unless it is a very bad case, you will not require salt,for you can put this down to 34 above zero, tivo degrees above thefreezingpoint,'with icc alone.

Having thus given a full and eact description ofmy improvedcorpse-prescrver, n'hat I claim as new, and desire to secure by LettersPatent, is l. Y

I. The application ofA u tubular iee-box to a corpse-preserver, whetherthe same be made with openings near the bottom or ou the bottom, orwhether the same be made tight, und you get your cold by conduction,substantially as herein described, und delineated on the drawingshereunto annexed.

2,. I claim the construction of the corpse-preserver, substantiallyin'fthe manner set forth inthe drawing, und described in thespecification, of getting the rotation or movement of the air in thechamber A, substantially as described. I i Y 3. I claim the combinationof the tubes or pipes Enith th as herein described, and for the purposesherein set forth. CHARLES F. PIKE;
